Free will means to choose to live with or without God. If you choose to live without God by being unfaithful to His Word then you will be as Cain who God set outside the presence of HIM into the wilderness to walk as just a wanderer in the earth and learning how to provided, protect for your ownself and will eventually die as is the result of being your own god.
If you chose to accept, believe and follow Christ.. God's Word then you will walk in a good life for God is not a child abusing Father but He cares for His OBEDIENT children who look to HIM for their successes in life doing things according to His Word even when it hurts, they still remain faithful knowing that victory comes by abiding in His Word and His Word in them because the Father sees all and is our Source for all power and things come from Him not of ourselves.
Before the foundation of the world means that God created us in the beginning to be godly children whom He can bless with good health, abundance in all things so that we do not need to steal, kill or destroy to live in peace, provision and protection as the fallen nature does who have not made the Lord their Hand to receive these things, but use their own or other men's hands to gain in this life.
We have been a fallen creation since Adam disobeyed God's Word so the LORD removed Adam far from the Tree of Life who is the Word of Life being Christ. For when God wants man to understand the goodness of His Word.. He removes it from them so that they fall into deep darkness for us to see the effects of our famine for the Word.
Eve was in deception because she received God's Word second hand.. but we now have the opportunity to be restored given the free will choice to receive Christ the Word of life whom was manifested in the flesh, and many who pure heartedly do are being chosen before the foundation of the NEW world to come but we now being born again of the Spirit and separated from our mother's womb(heavenly Jerusalem) to be raised up meaning trained up in the Word by the Wisdom of God(Spirit) to be kings and priests of the new earth. We begin as babes but as we grow in Christ aka The Word we grow in integrity and grace to prepare us for our positions in the kingdom of God to rule all nations in the knowledge of God who is not only the Head but must be the center of our life if we plan to remain alive. For when we choose with our Free Will to live without God the results are not good~ But with God all is possible and unlimited as to the good things He gives to one who LOVES THE SON and abides in The Word all the days of their lives keeping the Word alive in the earth.
Deut 30:19-20
19 I call heaven and earth to record this day against you, that I have set before you life and death, blessing and cursing: therefore choose life, that both thou and thy seed may live:
20 That thou mayest love the LORD thy God, and that thou mayest obey his voice, and that thou mayest cleave unto him: for he is thy life, and the length of thy days: that thou mayest dwell in the land which the LORD sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give them.
KJV
Gen 28:3-4
3 And God Almighty bless thee, and make thee fruitful, and multiply thee, that thou mayest be a multitude of people;
4 And give thee the blessing of Abraham, to thee, and to thy seed with thee; that thou mayest inherit the land wherein thou art a stranger, which God gave unto Abraham.
KJV
Gal 3:11-16
11 But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith.
12 And the law is not of faith: but, The man that doeth them shall live in them.
13 Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree:
14 That the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith.
15 Brethren, I speak after the manner of men; Though it be but a man's covenant, yet if it be confirmed, no man disannulleth, or addeth thereto.
16 Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.
KJV
